Abstract
An optical fiber amplifier for controlling gain flatness including an optical fiber amplifying unit for amplifying input signal light according to a predetermined amplification control value, a measuring unit for measuring the power level of amplified spontaneous emission (ASE) at a predetermined wavelength band output from the optical fiber amplifying unit, and a gain controller for controlling the amplification control value of the optical fiber amplifying unit according to the measured power level of the ASE to flatten the gain of the optical fiber amplifying unit. The gain flatness of amplified signal light is monitored and controlled, thereby obtaining gain-flattened signal light even when power level of signal light varies from wavelength to wavelength.
